Hiring a remodeling contractor is one of the highest-stakes vendor decisions most homeowners ever make. Unlike buying a product, you're entering a relationship that lasts months and involves your home, a significant amount of money, and people you'll interact with daily. The right questions asked before signing reveal more than any review site can. Here are the ten that matter most.
In Arizona, any contractor doing work over $1,000 must be licensed by the Registrar of Contractors (ROC). The license number can be verified instantly at roc.az.gov — which shows the license type, current status, any complaints filed, and whether they're bonded.
What you're looking for: An active B-1 (residential general contractor) or B-2 (residential remodeling) license. Verify it yourself rather than taking the number at face value.
Red flag: Any contractor who hesitates, doesn't know their number, or suggests a permit isn't needed for work that clearly requires one.
A legitimate remodeling contractor carries two types of insurance: general liability (covering property damage or injury during the project) and workers' compensation (covering their employees if injured on your property). Both should have your property listed as an additional insured on the certificate.
What you're looking for: A certificate of insurance from the carrier directly, listing your address and naming you as additional insured. Minimum general liability for a remodeling project should be $1M per occurrence.
Red flag: A contractor who says they're "self-insured" or can't produce a certificate within 24 hours.
Some contractors sell the job and hand it off to a project manager you've never met. Others are the person on-site daily. Either can work — but you need to know which it is before signing, and you need one identifiable person who is responsible for your project.
What you're looking for: A named project manager or lead carpenter with direct contact information. Clarity on who you call when something comes up.
Red flag: Vague answers ("our team will handle it") or a contractor who seems unsure who will actually be running the job.
The contractor should pull permits under their license for any work that requires them. Work done without permits creates problems at resale and leaves you with no recourse if work fails inspection retroactively. A contractor who suggests "going without a permit to save time" is protecting themselves at your expense.
What you're looking for: A clear answer that they pull permits and schedule inspections as part of the project. This should be reflected in the contract.
Red flag: Suggesting permits aren't necessary for work that clearly requires them, or asking you to pull the permits yourself (this shifts liability to you).
Online reviews give a general picture, but references from homeowners who had a similar project scope (kitchen remodel, bathroom addition, whole house renovation) give you specific insight. A contractor confident in their work will have no issue providing three to five references and encouraging you to call them.
What to ask references: Did the project come in on budget? On time? Were there surprises, and how were they handled? Would you hire them again? Can I see the finished work?
Red flag: Hesitation to provide references, only providing references from very small or very old projects, or references who seem coached.
Changes during a remodel are normal — materials get discontinued, hidden conditions require scope adjustments, and clients change their minds. How a contractor handles those changes matters as much as the original contract. The right answer is a formal written change order process: no work proceeds on a change without a signed written order specifying the cost and timeline impact.
Red flag: "We'll figure it out" or a contractor who doesn't mention a change order process at all. Undocumented scope changes are the primary source of disputes between homeowners and contractors.
Legitimate contractors structure payments around project milestones, not arbitrary dates. A typical structure: a deposit at signing (10–30%), a draw at demo or rough-in completion, another at a mid-project milestone, and final payment at project completion and punch list sign-off.
Red flag: A request for 50%+ upfront before work begins, or a contractor who needs a large deposit to "order materials" before a contract is signed. Established contractors have supplier credit — they don't need your money to buy materials before starting.
In Arizona, plumbing and electrical work must be performed by separately licensed tradespeople (plumbing: C-37; electrical: C-11). A general contractor who uses licensed subs for these trades is following correct practice. Ask specifically whether the people doing your plumbing and electrical hold Arizona trade licenses.
Red flag: A contractor who does "all trades in-house" on a project that includes plumbing and electrical, without clarifying that those individuals hold the appropriate Arizona trade licenses.
A reputable contractor stands behind their work. Arizona law requires a one-year workmanship warranty under the ROC, but many quality contractors offer longer warranties — two years on labor for most trades. Ask what the warranty covers and what the process is for warranty claims.
What you're looking for: A clear, specific answer — not just "we guarantee our work." A contractor who has done warranty repairs for past clients and can reference that as part of their process is a strong signal.
Construction in an occupied home produces dust, debris, and foot traffic. How a contractor manages that affects both your daily life during the project and the condition of the rest of your home when work is done. Ask specifically about dust barriers, daily cleanup practices, floor protection, and end-of-day conditions.
What you're looking for: A specific answer — zip walls and dust barriers for demo phases, daily sweep, covered HVAC vents during demo. A contractor who hasn't thought about this hasn't done many occupied-home projects.
The questions above aren't just checklist items — they're signals of how a contractor operates. A licensed, insured contractor who can articulate their process for permits, change orders, subcontractors, and warranties has thought seriously about how they run their business. One who hedges or can't answer specifically is telling you something.
The goal isn't to find a contractor who answers every question perfectly — it's to find one you trust enough to give access to your home for several months. These questions help you get there faster.
Three is the standard recommendation. More than three is usually not productive — bid preparation takes time for both parties, and past a certain point you're comparing bids that differ in scope assumptions rather than price. Two bids can work if you've done due diligence on both contractors and feel confident in the comparison.
Not automatically — but it's the bid that requires the most scrutiny. Ask what's in the low bid that the other bids include. Common omissions in low bids: permits, waterproofing membranes in showers, specific materials, cleanup. If the low bid is genuinely apples-to-apples and the contractor passes the above questions, it may be a legitimate best value. If it's low because scope is missing, you'll pay the difference in change orders.
For most remodeling projects, local is significantly better. A Prescott contractor knows Yavapai County permit processes, has relationships with local inspectors, uses local suppliers (faster material availability, no freight delays), and has a reputation to protect in the local market. A contractor from Phoenix doing a job in Prescott has a longer drive time billed to your project and less accountability in the local market.
